本考案は、丸鋸式切断機におけるターンテーブ

The conventional turntable fixing device in a circular saw type cutting machine simply presses the outer peripheral surface of a protrusion formed at the lower part of the turntable with a cylindrical pressing member.

Therefore, when cutting work with a circular saw type cutting machine having a turntable fixing device configured as described above, the outer diameter of the turntable fitted to the base and the fit formed on the base are Since there is a gap between the cylindrical pressing member and the inner diameter of the matching hole, the cylindrical pressing member cannot suppress vertical vibrations caused by cutting the workpiece, and the vibrations caused by cutting the workpiece increase. This significantly reduces cutting accuracy and work efficiency, and if cutting is continued under vibration, the impact cutting reaction force against the circular saw blade becomes excessive, causing damage to the saw blade.
本考案の目的は、上記した従来技術の欠点をな
くし、被削材切断作業の効率向上と鋸刃破損防止
を図るものである。 The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, improve the efficiency of workpiece cutting work, and prevent damage to the saw blade.

In the present invention, a V-groove is formed on the outer peripheral surface of the protrusion of the turntable substantially parallel to the top surface of the turntable, and a pressing member mounting hole is formed on the side surface of the base at a position slightly below the center position of the V-groove. This is achieved by forming a pressing member and removably providing a pressing member having a V-shaped protrusion at its tip in the pressing member mounting hole.

When the pressing member is screwed into the pressing member mounting hole, the V-shaped protrusion of the pressing member is inserted into the V-groove of the turntable. At this time, since the position of the pressing member mounting hole is slightly below the center position of the V-groove, the turntable is fixed toward the base by the pressing member.
